(BUILDING CODE OF AUSTRALIA) REGULATION 2009

PURPOSE This information bulletin is to inform the Asset Managers and Facility Planners in the Area Health Service of the commencement of the Building Code of Australia (BCA) 2009 and the Environmental Planning and Assessment Amendment (Building Code of Australia) Regulation 2009.

KEY INFORMATION • The Building Code of Australia (BCA) is amended on an annual cycle with each new

amendment beginning on 1 May of the relevant year. • The purpose of the BCA 2009 amendment is to make changes to Volume One

(Class 2 to 9 buildings) and Volume Two (Class 1 and 10 buildings). Please note Health Care Buildings are generally Class 9.

• In summary changes to the BCA 2009 include:

- Updating referenced documents. - Deleting all references to the older loading standards contained in the AS 1170

series (except for AS 1170.4 1993) and all provisions referring to them, due to the expiry of the agreed transition period.

- Simplifying the wire balustrade provisions, including the addition of a Verification Method.

- Clarifying how distances are measured in the construction of sanitary compartments to enable an unconscious occupant to be removed.

- Clarifying the required height of rooms with a sloping ceiling and in an attic. - Further update the energy efficiency provisions. - Include minor technical changes for clarity and consistency.

Commencement of the Building Codeof Australia 2009This circular is to advise councils, accreditation bodies, relevant government agencies,industry groups and other stakeholders of the commencement of the Building Code ofAustralia (BCA) 2009; and the Environmental Planning and Assessment Amendment(Building Code of Australia) Regulation 2009.

BackgroundThe Building Code of Australia (BOA) is amendedon an annual cycle with each new amendmentbeginning on I May of the relevant year.BCA 2009, which commences on 1 May 2009, isgiven legal effect in NSW through theEnvironmental Planning and Assessment Act 1979(EP&A Act) and the Environmental Planning andAssessment Regulation 2000 (EP&A Regulation),which call-up' the BCA as amended from time-to-time.BCA 2009 does not contain any major reforms,however, it incorporates amendments identifiedthrough the Australian Building Code Board's(ABCB's) Proposal For Change process. The BCA2009 changes provide the opportunity to focus onissues of clarification and better understanding,and application of the BCA, which is ofconsiderable benefit to all stakeholders and endusers of the BCA.

It should be noted in relation to places of publicentertainment that a package of reforms for theregulation of entertainment is currently beingdeveloped by the Department, which includes thedefinition of a new term 'entertainment venue'.While the reform package is not yet completed, theterm 'entertainment venue' has been included inthe NSW Appendix of BCA 2009-however, itsimplementation is delayed until the EP&ARegulation is amended as part of these reforms.Further information will be issued on this at a laterdate.

BCA 2009The purpose of the BCA 2009 amendment is tomake changes to Volume One (Class 2 to 9buildings) and Volume Two (Class 1 and 10buildings) as follows.In both Volumes:• update referenced documents

delete all references to the older loadingstandards contained in the AS 1170 series(except for AS 1170.4 1993) and all provisionsreferring to them, due to the expiry of theagreed transition period

• simplify the wire balustrade provisions,including the addition of a Verification Method

• clarify how distances are measured in theconstruction of sanitary compartments toenable an unconscious occupant to beremoved

• clarify the required height of rooms with asloping ceiling and in an atticfurther update the energy efficiency provisionsinclude minor technical changes for clarity andconsistency.

In Volume One only:clarify the application of the vertical separationprovisionsclarify the intent of separation of equipment.

BCA 2009-NSW AppendixThe purpose of amendments to the NSWAppendices is to make changes, as follows.In both Volumes (NSW Appendices):• include a new footnote under Electrical

Installations.

Department of Planning circular BS 09-002

In Volume One (NSW Appendix) only:delete NSW C3.2(a) due to it beingincorporated into the main BOAmake editorial changes to a number ofreferences to Subsection J(A) and J(B)amend all references to public entertainment inthe NSW Appendix, to read 'entertainmentvenue' as follows:- replace the definition of place of public

entertainment with a new definition of'entertainment venue' which refers to thedefinition under the EP&A Regulation

- amend other definitions, as appropriate,to substitute the new term 'entertainmentvenue'

- delete references to place of publicentertainment wherever occurring in theNSW Appendix and replace them with thenew term 'entertainment venue'.

Note: a number of these replacements have beenomitted in BOA 2009-NSW Table D 1.13 and thetitle to NSW Part H 101. It was intended that theseprovisions also refer to the new term 'entertainmentvenue'. This will be rectified with BOA 2010.

EP&A Amendment (Building Codeof Australia) Regulation 2009The EP&A Amendment (Building Oode of Australia)Regulation 2009, published on I May 2009, delaysthe commencement of all the amendments thatapply the term 'entertainment venue', as describedin the above section (BOA 2009-NSW Appendix),until such time as the EP&A Regulation is amendedto make provision for entertainment venues.

As a 'savings and transitional regulation', EP&AAmendment (Building Oode of Australia)Regulation 2009 ensures that until the definition of'entertainment venue' is included in the EP&ARegulation, the BOA will continue to apply-as if theamendment of the term had not been made. Thepractical effect of the regulation amendment is thatthe defined term 'place of public entertainment' andits use in BOA 2008 will continue to apply until'entertainment venue' is defined in the EP&ARegulation.

Further informationThe ABOB's List of Amendments for each volume,listing each individual change made under BOA2009 is attached to this circular.It is also the Department's intention to issue afurther circular on BOA 2009 at a later date toprovide practitioners with more comprehensiveinformation on the changes to the BOA and theirapplication in NSW.

comply with Table J4.2 for the floor area of the adjoining room and the proportionof the habitable room that is ventilated from the adjoining room.

J5.2(a)(vi) and new Amended to better cover more conventional systems due to the existingTable J5.2a provisions being found to be too restrictive for specialised applications where

there is a high internal load such as a computer suite or a telephone exchange.The changes include the addition of a new Table J5.2a.

J5.2(a)(vii)(A) The reference to J5.4(c) has been deleted due to that provision settingrefrigeration performance and not fan efficiency as covered by J5.2(a)(vii). Thesubsequent provisions have been re-numbered.

J5.2(b)(i) Due to the occupants of sole-occupancy units in Class 2 buildings and Class 4parts of buildings usually controlling any mechanical ventilation system, theprovision has been amended to exempt these parts of a building from therequirement for such systems to be capable of being inactivated when thebuilding is not occupied.

J5.2(b)(iii)(A) As a consequence of the change of Table number, the reference to Table J5.2has been amended to Table J5.2b.

Table J5.2 As a consequence of the inclusion of new Table J5.2a, Table J5.2 has beenre-numbered Table J5.2b.

J5.3 Amended to limit the requirement for a time switch so that one is not requiredwhere the air-conditioning or ventilation system serves a sole-occupancy unit in aClass 2 or 3 building, a Class 4 part of a building or a Class 9c building. Thereason for this is that Class 2 buildings and Class 4 parts are privately ownedresidential buildings and likely to be closely controlled by the occupants. Thesole-occupancy units of a Class 3 building are already controlled by an occupantactivated device and likely to be controlled by the occupant when they are inresidence while staff and public areas are likely to be in use. Class 9c buildingsare also likely to be closely controlled 24 hours a day.

Likewise, a time switch is not required where air-conditioning or ventilation isneeded for 24 hour occupancy as it is likely to be of little use.
